Abstract (en)

[origin: EP0701226A2] Image analysis techniques supporting the determination of spatial areas including segmenting textual areas (Figs 7,9) into particular lines of text are disclosed, in which a line height and position is estimated (380) based on a first token. Each succeeding rightward token is analyzed (382-386) according to its proximity to the current line position estimate. Tokens whose vertical position are within a desired proximity (392) to the position of the line are accepted (398) as part of the line, and a new line estimate is made (399) before proceeding to the next token. Questionable tokens, which are near but not within the desired proximity, are accepted (388) if they touch an accepted token. <MATH>
